AWS EC2, pm2 : Cannot see pm2 running list

Question

I'm using Amazon Linux AMI 2017.03.1 (HVM), SSD Volume Type.

And I installed node.js, npm via the way like this below because I want to install globally and if I don't install pm2 globally, it doesn't work when I configure EC2 bootstrapping launching pm2 command.

After that I created my own AMI image.

### node.js, npm install ###
  $ sudo su
  $ curl --silent --location https://rpm.nodesource.com/setup_6.x | bash -
  $ yum -y install nodejs
### pm2 install ###
   $ npm install pm2 -g

and here is my user-data text at 'Advanced Details' when i create new EC2 instance via my own AMIs.

### user-data ###
 #!/bin/bash
 cd /home/ec2-user/Node.js-Test
 sudo git pull origin master
 export PM2_HOME=/home/ec2-user/
 sudo env PATH=$PATH:/usr/bin/ pm2 startup systemv -u ec2-user --hp /home/ec2-user
 su ec2-user
 pm2 start /home/ec2-user/Node.js-Test/app.js
 pm2 save

so when I launch new EC2 instance with this configuration above, pm2 command is working but I cannot see the running pm2 list.

When I checked the log file /var/log/cloud-init-output.log, it has info of running pm2 application!

### /var/log/cloud-init-output.log ###
 [PM2] Spawning PM2 daemon with pm2_home=/home/ec2-user/

but I cannot see that running pm2 list @ec2-user, @root

Does anyone who know this issue and solution??? Thanks.

Answer 1

I changed several commands in EC2 User-Data like

#!/bin/bash
cd /home/ec2-user/Node.js-Test
sudo git pull origin master
sudo pkill -f PM2
sudo pm2 start /home/ec2-user/Node.js-Test/app.js
sudo pm2 startup
sudo pm2 save

and I can see pm2 list now typing sudo -i pm2 list. and shown empty list when i just typed pm2 list.

[ec2-user@ip-172-31-14-68 .pm2]$ sudo pm2 list
┌──────────┬────┬──────┬──────┬────────┬─────────┬────────┬─────┬───────────┬──────┬──────────┐
│ App name │ id │ mode │ pid  │ status │ restart │ uptime │ cpu │ mem       │ user │ watching │
├──────────┼────┼──────┼──────┼────────┼─────────┼────────┼─────┼───────────┼──────┼──────────┤
│ app      │ 0  │ fork │ 2458 │ online │ 0       │ 11m    │ 0%  │ 29.3 MB   │ root │ disabled │
└──────────┴────┴──────┴──────┴────────┴─────────┴────────┴─────┴───────────┴──────┴──────────┘

And here is context of /root/.pm2/dump.pm2.

Thanks.
